The effect of salt water on Seed Germination

2nd grade life science: Students know many characteristics of an organism are inherited from the parents. Some characteristics are caused or influenced by the environment.

Students know light, gravity, touch, or environmental stress can affect the germination, growth, and development of plants.

Biology:

Students know a vital part of an ecosystem is the stability of its producers and decomposers.

Students know at each link in a food web some energy is stored in newly made structures but much energy is dissipated into the environment as heat. This dissipation may be represented in an energy pyramid.

* Students know how to distinguish between the accommodation of an individual organism to its environment and the gradual adaptation of a lineage of organisms through genetic change.

Investigation/Experimentation:

Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other four strands, students should develop their own questions and perform investigations.
